Hi, Your daughter is just 2 year old, advised Pre-pro kid sachets, laxiwal and a tonic but no relief from diarrhea for three days, also getting Sinarest for cold. I would advise you the following: Your Pediatrician seems this to be due to a viral infection or intolerance to something that is why the diarrhea is not getting controlled. Send the stool and blood sample for tests. If there is any evidence of an intestinal infection then she will need additional antibiotic coverage. Continue the management as already she is on. Proper hydration is very important and this is possible as there is no nausea or vomiting. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, General Surgeon
